Following successful installations in China, TTC Inc. is keen to
establish itself in other parts of the Asia-Pacific region.
facilitate this, and demonstrate TTC’s capability in both system
upgrades and new equipment, TTC is offering a system based around a
refurbished scanner with TTC’s “plug and play” supporting
measurement and control infrastructure.
The refurbished scanner can accommodate a web width of 3.96 metres, and sensors for grammage, moisture, thickness, colour, etc.
your company is considering upgrading or replacing an existing QCS, we
should be able to provide a quotation that will be attractive to you.
If you are interested in pursuing this cost-effective application of modern technology, then Contact Procex!

The planning of grades to be produced on each paper machine or pulp dryer has been enhanced with dialogs that allow grades to be easily selected and re-arranged. Speeds and furnish percentages can be altered if current conditions result in operation different to standard rates and furnishes.
Washer dilution factor optimization has been implemented in Pro-Plan. Because of the significant impact of washer dilution factor on evaporator and recovery boiler solids throughput, bleach chemical consumption and soda loss, Pro-Plan optimizes the dilution factors against cost and total mill production.
Another mill study shows that a 5% increase in pulp output would result from using Pro-Plan in that mill.
A Production Cost module has been added to Pro-Plan. It calculates the costs of steam, gas and power for the recommended strategy and displays a comparison with the equivalent costs for the current strategy. This is a component required for future total cost optimization.
Mill Studies have shown the degree of improvement possible resulting from the use of the Pro-Plan Pulp Mill & Recovery Optimization System:
One study indicated that pulp production would be increased by an average of 3.5%.
Another study indicated that bleach plant production could be increased by 5%, thus replacing purchased bleached pulp and saving around $700,000 annually.
Because of the evolution of the Pro-Plan Pulp Mill & Recovery Scheduling System into process efficiency improvement and cost minimization, it has been renamed as the Pro-Plan Pulp Mill & Recovery Optimization System.
Pronyx AB, a Swedish group focusing on industrial IT-solutions, has entered into an agreement to cooperate with Procex Pty Ltd of Melbourne Australia, to market, install and support the Pro-Plan Pulp Mill & Recovery Scheduling System in Scandinavia.
Pronyx AB develops tailor-made industrial IT-solutions for the process industry as a whole. Its subsidiary Pronyx Paper targets the pulp and paper industry.
Pronyx will promote the Pro-Plan product together with the Pronyx PaperLine, PulpMan & StabOpti concepts. The integration of these products will allow better coordination and optimization of the pulping/recovery and papermaking processes.
As well as balancing the steam supply and demand, PRO-PLAN now also allocates steam generation to power boilers and recovery boilers in the most economic manner. This will lower the operating cost of the mill.
The algorithms to determine the optimal time to schedule evaporator washes have been improved. PRO-PLAN now monitors the degradation of evaporator performance and determines the point at which evaporators should be washed to maximize the throughput over the longer term.
Another feature to maximize pulp mill output!
PRO-PLAN now includes other constraints beside those of production unit throughputs, liquor restrictions and storage level limitations.
Constraints now also include:
